A database is a structured collection of data that is organized in a way that enables efficient storage, retrieval, and manipulation of that data. It's like a digital filing cabinet that helps store and manage information systematically. In technical terms, a database typically consists of tables, which contain rows and columns to store specific types of data. It allows users to perform various operations on the data, such as adding new data (insert), retrieving specific information (select), updating existing data (update), and deleting unwanted data (delete). For instance, in a school database, you could have tables for students, courses, and grades. The students' table may include columns like student ID, name, and age, while the courses table could have columns for course ID, name, and teacher. By querying the database, you can retrieve information like a student's grades for a particular course. Examples of popular databases include MySQL, PostgreSQL, Oracle, and Microsoft SQL Server. These databases are widely used in various applications such as e-commerce websites, social media platforms, banking systems, and more to store, manage, and retrieve data efficiently.
